these kind of questions pop up ALL the time, please run throught Liver-Flush FAQ, esp with R and R/N conotations and ALL your answers will be answered; please dovote some time to that.
Also, I would think it would be a good idea for the Webmaster to put a colored sentence that all people posting same and same question all over and over again would see and know links and answers BEFORE they ask the same question.
lisag, where did you get the idea that olive oil is 100% cholesterol? if it is true then I have ten wings on each of my shoulder blades and I can fly at the speed of an F-16. As long as olive tree doesn't have a liver it shouldn't be the case.
